SPECIFICATION
A bottomed tubular parison for a bottle The present invention relates to a bottomed tubular parison for a bottle, and to a bottle produced from the parison and a method of making the bottle.
It is known to produce a thin-walled bottle of a synthetic resin by a blow moulding process to biaxially orient a parison which is prepared by injection moulding a synthetic resin material into a bottomed tubular shape. The bottle thus biaxially oriented has a small weight but a high mechanical strength as well as other excellent physical prop- erties. As a result, the thin bottle thus produced can store various liquids including a liquid having an increasing internal pressure such as a carbonated beverage.
When the parison thus prepared is to be blow- moulded so that it may be biaxially oriented, it is usual that the parison has its bottom portion left so insufficiently oriented that the bott6m of the thin bottle after the blow moulding process is locally thickened. The bottom having an irregular thickness is deficient in mechanical strength and/or other physical properties.
In the case of the usual shape in which the bottle bottom is flat or slightly raised at its centre, it is known in the art that the oriented condition of the bottle bottom can be slightly improved if the bottom portion of the tubular parison is made in advance to protrude into a hemispherical shape. According to this prior art technique, however, the bottle bottom has its centre portion insufficiently oriented but its circumferential or corner portion oriented to have an excessively small thickness. Therefore, that technique is not acceptable in view of the resultant mechanical strength and other physical properties of the bottle product.
It is therefore an object of the present invention to provide a parison which can ensure the uniform thickness of the bottom of the bottle product, where the parison is biaxially oriented to produce the bottle, thereby to improve the mechanical strength and other physical propertibs of the bottle product.
Another object of the present invention is to provide a bottomed tubular parison which has its bottom portion protruding into such a hemispherical shape as to make the more uniform biaxial orienta- tion possible.
Afurtherobject of the present invention isto provide a bottomed tubular parison, in which the centre portion of the inner surface of the bottom portion thereof is formed into such a flat shape by the injection molding process that the thickness of the centre of the bottom wall may not be remarkably varied before and after the orientation even if the lug formed as the result of the pouring gate is thereafter cut away.
According to a feature of the present invention, there is provided a bottomed tubular parison for producing a bottle by biaxial orientation, said parison being prepared by injection-moulding a synthetic resin, wherein the bottom portion of the said parison gradually increases in thickness from the centre to the outer circumference thereof such that said bottom portion can be uniformly oriented at a similar orientation rate to that of the drum portion.
According to another feature of the present inven- tion, there is provided a bottomed tubular parison of type having the above feature, wherein said bottom portion is made to protrude into a generally hemispherical shape.
Other objects and advantage of the present inven- tion will become apparent from the following description made with reference to the accompanying drawings, in which:
Figure 1 is a partially broken front elevation showing a bottomed tubular parison for producing a bottle by biaxial orientation according to the present invention; Figure 2 is an enlarged longitudinal section showing a bottom portion of the parison of Figure 1; Figure 3 is a longitudinal section showing a bottom portion of a bottle which is produced by blow-moulding and biaxially orienting the parison of Figures 1 and 2.
Figure 4 is similarto Figure 2 but shows a parison prepared according to the prior art; and
Figure 5 is similar to Figure 3 but shows the bottle which is produced from the parison of Figure 4.
A parison for producing a bottle by biaxial orientation according to the present invention will be described with reference to Figures 1 and 2.
The parison, as indicated generally by reference numeral 1, is prepared by subjecting a synthetic resin to an injection moulding process so that the resin may be moulded into a tubular shape having a bottom portion 2. The most suitable synthetic resin for this purpose is a saturated polyester resin, but a resin such as polypropylene or polyvinylchloride can also be employed. The parison 1 has its upper portion formed into a mouth portion 3 which has the final shape because it is not subjected to biaxial orientation, unlike the lower drum portion 4.
The bottom portion 2 of the parison 1 is made to protrude from the drum portion 4 into a hemispherical shape. It should be noted here that the hemispherical bottom portion 2 is made such that the radius of the outer spherical surface is largerthan that of the inner spherical surface. For this purpose. more specifically, the centre of radius of curvature 01 of the inner spherical surface 2a is positioned below the centre of radius of curvature 02 of the outer spherical surface 2b so that the thickness of the bottom portion 2 is made gradually larger from the centre to the outer circumference thereof.
The centre portion 5 of the inner surface of the bottom portion 2 is formed into a flat shape within a limited small area. This is because the centre portion 5 can be prevented from having its thickness from being markedly varied and its strength from being reduced even if the trace of the gate of an injection moulding machine is cut away after the parison 1 is injected-moulded while placing that particular gate on the centre portion of the outer surface of the bottom portion 2.
When the parison 1 thus prepared has its portion other than the mouth portion 3 subjected to the blow moulding process of the biaxial orientation type, the 2 GB 2 040 216 A 2 biaxial orientation is first effected in the thinest centre 6 of the bottom portion 2 and is then gradually propagated to the thicker outer circumference.
As a result, even the bottom portion, which has failed to be sufficiently oriented according to the prior art, can be sufficiently oriented at a similar orientation rate to that of the drum portion. As shown in Figure 3, therefore, the bottom B of the bottle product A can be uniformly oriented as a whole without being locally excessively thinned so that it has improved mechanical strength and/or other physical properties.
On the other hand, in the case where the bottom portion 2'of a parison 1'does not have its thickness locally varied but has a uniform thickness, as shown in Figure 4, the desired uniform orientation cannot be attained. The orientation condition established according to the prior art is, as shown in Figure 5, such that the centre portion of the bottom B of the bottle product A is insufficiently oriented whereas the circumferential or corner portion is oriented to have excessively small thickness.
As has been described hereinbefore, according to the present invention, since the thickness of the bottom portion of the parison is made gradually largerfrom the centre to the outer circumference thereof, the biaxial orientation is started at the centre of the bottom portion and is propagated to the outer circumference. As a result, the bottom portion can be sufficiently biaxially oriented thereby to have a uniform thickness so that it can have its mechanical strength and other physical properties improved.
Moreover, since the bottom portion of the parison is made to protrude into the hemispherical shape, its orientation can be brought into more uniform condition than the prior art. Still moreover, since the centre portion of the inner surface of the bottom portion of the parison is formed into a flat shape, it can be oriented without any considerable change in the thickness even if the portion corresponding to the pouring gate is cut away after the injection moulding process of the parison.
According to the present invention, on the other hand, a special device need not be added for sufficiently orienting the bottom portion of the parison, and the material required for the moulding process of the parison can be reduced so as to reduce the production cost.
